A very good trick in an emergency, though if you're prepping for the Zombie Apocalypse you should stock lots of REAL fish hooks (not to mention extra lures, tackle, line, poles & some cheap Zebco reels. My two ponds will be our main source of food after the grocery stores are looted & burning, so I have LOTS of extra fishing tackle -- and enough ammunition to protect my food supply. Fish hooks are CHEAP. A couple of bucks will buy you enough to last for a dozen years, probably.

But still a great idea if you're suddenly stuck away from home & your usual supplies. Pop-top cans are everywhere, so if you have a couple of tools, or a Leatherman pocket tool, you're in business.

Might increase the strength of these (for bigger fish) by doubling up, tying two of these hooks together on the line, holding one piece of bait.

Yes, I agree. In fact, in Australia my understanding is that non-rusting fish hooks are not allowed (I am sure someone will correct me if I am wrong) - the idea is that if a line breaks eventually it will rust away, but I shouldn't want to wait that long if I had a hook in my cheek.

Who cares if it rips the fish up. When you need to fish with one it will problay be survival situations so I don't think you would be to worryed about the fish as long as it got to shore and you got a feed.

Good point. Still, I'm kind of a sap, I file the barbs off of my fish hooks. You know, you can poke a pin through your own cheek and it doesn't really hurt. The barb can cause some damage if the fish pulls loose and this hook looks a little likely to come loose. Still, I would definitely keep it in mind for real survival situations.

cleaver idea but it doesn't work for catching fish i did make a tool holder though with these mounted to a piece of wood (warning these are not very strong and only work for light stuff like a screw driver of pliers

If you had typical fishing gear, you could put a lead sinker on the line, which would take the hook under the water...If the entire getup is survivalist, though, I imagine you could perhaps tie a rock to the sting near the hook, or something else heavy, like if you had/found a metal bolt or screw lying around. Also, the weight of the bait should help it sink.
